The process of sweet oranges (Citrus x sinensis) into orange fruit juice gives benefits for the community because at the harvest time, sweet orange fruit prices fell and people can sell as fresh orange juice or as raw material for processing drinks. People still struggle with cheap squeezing machines. This research was a continuation of previous research with the title design of an orange juice extract machine for small-scale industries. This machine was made at a low price, made from local materials, easy to maintain, and can be applied for sweet orange farmers and small-scale industries. The aim of this research was to perform performance tests for sweet orange stripping and squeezing machine. The research method in this machine testing used a combination of big size Semboro sweet orange (Ø 65 mm), small size Semboro orange (Ø 49 mm), peeled orange, and orange not peeled. Each combination of treatment uses 16 kg of sweet orange fruit and was repeated three times, then the extraction yield and extortion work capacity were calculated. The results of testing the extracts of sweet orange fruit extracts showed that the testing of big size sweet oranges (Ø 65 mm) without peeling resulted in fruit juice yield of 33.8%, with a working capacity of 167.3 kg/hour.

Katuk leaves [Sauropus androgynus (L.) Merr] and moringa leaves (Moringa oleifera Lam.) are plants that can be used as galactagogues. Galactagogues compounds in both can stimulate the hormones prolactin and oxytocin, thereby increasing milk production. Katuk leaves and moringa leaves have a natural taste that is not favoured so that processing and formulation of other ingredients are needed to make the two ingredients more preferable. With an average growth from 2016-2020 of 4.250%, cookies can be a medium to help meet human needs. This study purposed to determine the level of preference and nutritional value of cookies with the addition of katuk leaves and moringa leaves as a snack for nursing mothers. This study used a factorial research design with 2 factors, namely 3 levels of katuk leaf flour (5 g, 10 g, 15 g) and 2 levels of moringa leaf flour (5 g, 10 g). The hedonic test data were processed using the Friedman test and further test with the Wilcoxon signed-rank test. Calculations used to test the effectiveness to determine the selected formula showed that the F4 treatment (5 g katuk leaf flour: 10 g moringa leaf flour) had the highest effectiveness value of 0.95. The results of the chemical test on the F4 treatment had a water content of 1.02%, carbohydrates 76.88%, protein 12.05%, fat 7.85%, and energy contributions of 423.50 kcal per 100 g, and 105.87 kcal per dose serving (30 g).

Riau is a province in Sumatra Island with the widest peatland covering up to ± 4,04 million Ha or about 56,1% of the area, with various type of peat, including the potentially submerged peat area. With the peat charasteristics drawbacks such as low nutrient content and relatively high acidity, cause this type of land barely cultivated for horticulture crop such as shallot. Whilst, in Indonesia, shallot is part of daily society culinary component. Therefore, efforts are needed to make use of peat land for this type of commodity by overcoming the shortages, for example by applying Trichocompost combined with Grand-K fertilizer. This research thus aimed at evaluating the growth and yield of shallot in potentially submerged peat soil, treated with Trichocompost and Grand-K Fertilizer. Experiment was conducted on peat soil in Labersa Street Kelurahan Simpang tiga Kecamatan Bukit Raya Kota Pekanbaru for three months, from October to December 2019. The experiment was arranged in completely factorial design with two factors; each at four levels. The factors were Trichocompost (at 0, 2, 4, 6 ton ha-1) and Grand K fertilizer (at 0, 50, 100, 150 kg ha-1). The parameters observed were the percentage of seed viability, plant height, number of leaf, number of tuber, and the yield per plan. Results of the experiment showed that the best combination of treatment was Trichokompos at 4 – 6 ton ha-1 dan Grand K at 150 kg ha-1.
廖内省是苏门答腊岛上泥炭地面积最大的一个省，面积达±40.4万公顷，约占总面积的56.1%，泥炭地类型多样，包括潜在的淹没泥炭区。由于泥炭的特点，其养分含量低、酸度较高等缺点，导致这类土地很少种植大葱等园艺作物。然而，在印度尼西亚，葱是日常社会烹饪的一部分。因此，需要努力利用泥炭地来生产这类商品，克服短缺，例如施用毛堆肥和大k肥。本研究旨在评价毛堆肥和大k肥处理下潜在浸没泥炭土中大葱的生长和产量。试验于2019年10月至12月在Kelurahan Simpang tiga Kecamatan Bukit Raya Kota Pekanbaru的Labersa Street泥炭土上进行，为期三个月。试验采用两因素全因子设计;每个都有四个层次。影响因子为毛堆肥(0、2、4、6 t hm -1)和大K肥(0、50、100、150 kg hm -1)。观察的参数为种子存活率、株高、叶片数、块茎数和单株产量。试验结果表明，滴虫4 ~ 6吨hm -1、大K 150kg hm -1处理组合效果最佳。

The results of this study exhibited that the treatment of 1 ml L-1 liquid fertilizer + 2 mg L-1 foliar fertilizer produced 9.30 shoots/explant and 1.90 leaves/explant, that no significantly different from MS medium (control) which produced 9.0 shoots/explant and 0.3 leaves/explants. Therefore, the using completed liquid fertilizers and foliar fertilizers as medium in vitro propagation of barangan bananas can become an alternative replace MS medium, as well as reduced the cost of culture media as 91% -93% compared to MS media.","PeriodicalId":340373,"journal":{"name":"Jurnal Agroteknologi","volume":"691 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2021-08-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"133199588","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

In several countries, moringa leaves are starting to be widely used in food products as an alternative to overcome malnutrition. Malnutrition occurs due to a lack of energy and protein balance which disrupt human physiological function. The lack of micronutrient intakes, such as vitamin A, iron, and zinc, can also cause malnutrition. Moringa oleifera is referred to as the most economical tree. Almost every part of the tree contains abundant nutrients and plays an important role in meeting human nutritional needs. Moringa leaves contain high protein, vitamins, and minerals, to be used as an alternative to overcome nutritional problems. Various studies have concluded that moringa leaves can be used in food products. This review aims to determine the use of moringa leaves to increase the nutritional content in food products. The addition of moringa leaf powder causes a significant increase in protein, fiber, and mineral content in several food products. The addition of moringa leaf powder with the highest concentration resulted in the best increase in protein, fat, fiber, and mineral content in several food products. However, the acceptable concentration of moringa leaf powder addition is not more than 5%. Keywords: mineral content, moringa leaf, nutrient

Robusta coffee is widely cultivated in Indonesia, and it is often processed into ground coffee. In this study, coffee jelly candy was made for product diversification of coffee. In this case, gel forming agents and sugar are needed to build jelly candy texture, aroma, and taste. The aim of this research was to study the characteristics of coffee jelly candy as affected by sucrose concentration and the ratio of carrageenan to gelatin. A completely randomized design using two factors (sucrose concentration of 40% and 60%; and gelatin to carrageenan ratio of 25:75, 50:50, and 75:25 w/w) was employed. The result showed that sucrose concentrations and gelatin to carrageenan ratio significantly (α > 5%) affected texture, color, moisture content, ash content, and organoleptic parameters (preference towards color, texture, taste, and overall). However, sucrose concentration and the ratio of gelatin to carrageenan not significantly (α < 0,05%) affect antioxidant activity and polyphenol concentration. The effectiveness test showed that coffee jelly candy with 40% sucrose concentration and the ratio of gelatin:carrageenan 50:50 had the highest score with L (lightness) value of 46.79, hardness of 54.53 g/mm, moisture content of 19.26%, ash content of 1.36%, antioxidant activity of 26.63%, total polyphenol of 0.46 mg GAE/mL, preference towards color of 5.60 (rather like), preferences towards aroma of 5.83 (rather like), preferences towards taste of 5.10 (rather like), preferences towards texture of 5.13 (rather like), and overall preference of 5.57 (rather like).
